Vertex and CRISPR Therapeutics Announce Authorization of the First CRISPR/Cas9 Gene-Edited Therapy, CASGEVY (exagamglogene autotemcel), by the United Kingdom MHRA for the Treatment of Sickle Cell Disease and Transfusion-Dependent Beta Thalassemia - Seite 2

About Beta Thalassemia
Beta thalassemia is an inherited blood disorder that affects the red blood cells, which are essential for carrying oxygen to all organs and tissues of the body. A lack of red blood cells, also known as anemia, is the primary manifestation of beta thalassemia. Because of this anemia, people living with beta thalassemia may experience fatigue and shortness of breath, and infants may develop failure to thrive, jaundice and feeding problems. Complications of beta thalassemia can also include an enlarged spleen, liver and/or heart; misshapen bones; and delayed puberty. Treatment for beta thalassemia is personalized and depends on the severity of disease that each person experiences. Many people have to get regular blood transfusions to deliver healthy donated blood to their body. This requires many hospital visits and can also lead to an unhealthy buildup of iron. Today, stem cell transplant from a matched donor is a curative option but is only available to a small fraction of people living with beta thalassemia. Beta thalassemia requires lifelong treatment and significant use of health care resources, and ultimately results in reduced life expectancy, decreased quality of life and reduced lifetime earnings and productivity. In the U.K., the mean age of death for people living with TDT is around 55.

About CASGEVY (exagamglogene autotemcel [exa-cel])
CASGEVY is a genetically modified autologous CD34+ cell enriched population that contains human hematopoietic stem and progenitor cells edited ex vivo by CRISPR/Cas9 at the erythroid-specific enhancer region of the BCL11A gene.

The latest data from the ongoing pivotal trials was presented at the European Hematology Association Congress in June 2023.

Exa-cel is also under review by the European Medicines Agency, the Saudi Food and Drug Authority, and the U.S. Food and Drug Administration (FDA). The FDA has granted Priority Review for SCD and Standard Review for TDT and assigned Prescription Drug User Fee Act (PDUFA) target action dates of December 8, 2023, and March 30, 2024, respectively.

About Conditional Marketing Authorizations
Conditional marketing authorizations (CMAs) are for medicines that fulfill a significant unmet medical need such as being for serious and life-threatening diseases, where no satisfactory treatment methods are available or where the medicine offers a major therapeutic advantage. A CMA is granted where comprehensive clinical data is not yet complete, but it is judged that such data will become available soon. CMAs are valid for one year and renewable annually with ongoing regulatory review of data.
